With the development trend of the manufacturing industry, the spiral air duct machine manufacturing industry is developing towards the direction of improving mold equipment, production process and design products. The technical performance of spiral air duct machines in China may be getting better and better. With the development of technology, people's requirements for the quality of ventilation and air conditioning projects are relatively improved. The existing spiral air ducts and spiral round air ducts are widely used, taking into account the functional requirements of ventilation and air conditioning projects and ash removal transportation.
This stipulates that we should carry out sustainable development in today's technology, select countermeasures that save raw materials and keep our physical and mental health sustainable, and carry out the development, design, production and manufacturing of machinery and equipment. At present, circular air duct and spiral air duct are the key to use metal air duct in central air conditioning ventilation duct. The circular tube has high compression strength and few consumables, but its manufacturing process is complex and takes up large indoor space; The spiral air duct is widely used because of its convenient layout and convenient production and processing. And mechanical automatic production of circular and rectangular frames made of steel chain spiral coil inductors. In order to save indoor space, many spiral air ducts are oblate.
In the natural ventilation and air conditioning system engineering, the friction resistance of gas fluidity is divided into two categories: one is the pressure loss caused by the viscosity of the gas itself and the friction with the wall thickness, that is, the friction resistance loss along the way; The other is the kinetic energy loss caused by vortex, that is, partial friction resistance loss, due to the change of water flow size and orientation due to the damage of symmetrical fluidity when the gas flows through a certain pipeline. Each air duct mode has its own advantages and disadvantages. The definition of arc air duct is clearly put forward for the places where it can be supplied and used. Arc duct comes from the control improvement of spiral duct and round duct. Get rid of the shortcomings of spiral air duct in terms of height width ratio of large indoor space required by circular air duct, such as raw material consumption, fluid power of spiral air duct, and large scale use of confined indoor space of section to save raw material consumption, reduce dust accumulation, and facilitate cleaning.
